The etymology of the scientific name "Allium cepa" can be broken down as follows:
- Allium: This is a Latin word that refers to garlic. It comes from the ancient Greek word "ἀλέω" (aleo), meaning "to avoid" or "to ward off". The name "Allium" was given to this genus of plants because many of them have strong, pungent smells that were believed to ward off evil spirits.
- Cepa: Also a Latin word, "cepa" means "onion". It is derived from the Classical Greek word "κάπια" (kápia), which refers to a leek or an onion. This word ultimately comes from the Proto-Indo-European language root *kāʔpyom.
So, "Allium cepa" essentially means "garlic onion" in Latin.
